Application filed September 16, 1913. Serial No. 790,073.

improvements in tiling tools, and as its principal object aims to provide a'deviceof this character' which Amay be' expeditiously operated to form grooves or beads v1n the surface of plaster or other wall coating, where-4 by the wall will present the appearance of',

tile blocks.

` A'further object is to provide a tiling implement or tool `constructed with such regard to number, proportion and arrangement of parts that it, may be cheaply manufactured, will be durable and efficient in its action, and may be readily 'employed-in forming the necessary .bead or--groove 1n all types of wall coatings, such as plaster and the they casewhen the coating is set'for some time.

. .The above and additional vobjects are accomplished by such means' as areillustrated in the accompanying drawings, describedI in the following specification' "and then more particularly pointed out in the claims which are appended hereto and 4form apart of this application.

y With reference to the drawings, wherein l have illustrated the preferred embodiment of my invention as it is reduced to practice,

i sponding parts,

- view of the tiling other coating and throughout'the several views of which similar reference`numerals designate corre- Figure 1 is a'perspective tool with the various elements in operative assembled relation; Fig. 2 is a side elevation illustrating the tool in operative-engagement with a wall; Fig. 3 is a section on the line 3-3 of Fig. 2; and Fig. 4 is a detail perspective view of the preferred form of knife blade which' is employed in cutting grooves in the plaster or to which the implement is ap lied.

roceedingnow to the description of the drawings, the numerals 10, 11 and 12 .designaterespectively the body or handle of the implement, 'the grooving knife,

y,plates which are adapted to be removably like, whether'it be softe as when rst ap-l plied, `or hardenedand brittle', asis usually and the face attached to the handle and arranged to clamp the knife in assembled position.

The handle 10 is preferably formed of a light metal, and includes a body or head 13 and a handle proper 14. The body or head portion 13 is preferably rectangular in shape throughout the major portion of its length, the upper and forward corner being cut away diagonally, however, as indicated at 15, for a purpose to be hereinafter more fully disclosed. In this connection it -is also to be noted that the lower forward corner is cut diagonally andinwardly toward the edge 15. The knife, as best illustrated in detail in Fig. 4, consists essentially in the U-shaped blade y11, the bight portion of which is formed with sharpened edges and the arms 17 of which are spaced from each other a distanceapproximately equal tov the thickness of the member 13.

The face plates 1.2 are substantially siinil lar in construction, each being shaped similarly to the member 13. One of the plates isvprovidedA with a pair of threaded apertures, as indicated at 18 and 19. These apertures are adapted to vregister' with apertures *formed in the handle head 13 and the second face plate. The apertures in the esA esl

second face plate are counter-sunk to receive the head of screws, indicated aty 20. It will be obvious upon reference to Fig. 3 that upon passing the screws through the apertures and threading them inward a sufficient distance, the face plates will actto clamp the arms 17 firmly against the opposite faces of the handle head 13.

Upon reference to Fig. 2, the purpose of cutting away the forward end of the head,-

as at 15 land 16, will be apparent. The bight portion of the knife is .adapted to be angularly adjusted with respect togthe head, so that the cutting edge of the bight portion will project any desired distance beyond the working face of the tool.

' ln'operation, the-working: face 21 of the l`tool is drawn over the surface'of Vthe plaster or other coating, so that the knife 11 will bite into the plaster, cutting4 a channelshaped groove. As the knife passes lthrough t-he coating, the ribbon or strip of material which is removed by the nife passes through the channel defined by the edge-16 -of the head 13 and the adjacent faces of the pointed terminalsy 23 and 24 of the face plates. Thus by cutting away the head at loe iis

working face of 'portion 14 of 'ficing any of the tion, as defined 1n l5 and 16,'V provision is made for the unrestricted passage of .the ribbon or coating 'which results from the drawing of the implement across the surface of the wall.

lt is desirable to call attention tothe fact that Athe knife may be adjusted. to bring its cutting edge any desired distance from the the tool by merely loosening the forward screws, moving the knife tothe desired position, and then retighten'- ing the said screws. v

, In the preferred embodiment, the shank the handle l() iscurved upwardly vand rearwardly from the head, so that the operators fingers maybe accommodated between the handle and the wall without contacting with the wall.

F-rom the foregoing, it willbe apparent that this invention provides a tiling implement formed of a minimum number of parts, ma be readily manipulated in a minimum time to adjust the grooving knife to the desired position.

In reduction to practice, l have found that the form of my invention, illustrated in the drawings and referred to in theabove description as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, l desire to emphasizethe fact that various minor changes in details of construction, proportion and arrangement of partsl may be resorted-to, when required, without sacriadvantages ofmy inventhe appended claims.

which are simple 1n construction, and,

mames i That I claim is i. In a tool of the character described, a polygonal body member having its forward corners cut-away to' produce a point, a pair of detachable, face plates,

forward corners of the body member and forming in connection with one edge of the body member a channel through which material may pass, and a U-shaped grooving knife adapted to be detachably secured to the body member by the face plates.

2. In a tool of the character described, a polygonal body member having its forward. corners cut inwardly and angnlarly with respect to the longitudinal axis of the body member, a pair of face plates having their forward terminals triangular in shape, the apeXes of the triangular portions extending c beyond the terminals of the body member,

and a U-shaped grooving knife adapted to be held in assembled position by the introduction of its arms between. the clamping plates and the adjacent faces of the body member, said knife being disposed adjacent the forward terminal of the body member, whereby the material removed by the knife escapes through the passage defined by the anexes of' the triangular portions of the face )lates and the adjacent angular edge of the body member.

In testimony ture in presence of two witnesses.
